The abstract, sentence by sentence
The generation of lepton asymmetry below the electroweak scale has a considerable impact on production of dark matter sterile neutrinos. Oscillations or decays of the heavier sterile neutrinos in the neutrino minimal standard model can give rise to the requisite lepton asymmetry, provided the masses of the heavier neutrinos are sufficiently degenerate. We study the renormalization group evolution of the mass difference of these singlet fermions to understand the degree of necessary fine-tuning. We construct an example of the model that can lead to a technically natural realization of this low-energy degeneracy.

The generation of lepton asymmetry below the electroweak scale has a considerable impact on production of dark matter sterile neutrinos. Oscillations or decays of the heavier sterile neutrinos in the neutrino minimal standard model can give rise to the requisite lepton asymmetry, provided the masses of the heavier neutrinos are sufficiently degenerate. We study the renormalization group evolution of the mass difference of these singlet fermions to understand the degree of necessary fine-tuning. We construct an example of the model that can lead to a technically natural realization of this low-energy degeneracy.

One of the important difficulties in the plain $ν$MSM setup is the generation of correct abundance of the DM sterile neutrino (see [ref] for a review), which requires very severe fine tuning in sterile neutrino sector [ref] or a special source of dark matter neutrino in the early Universe, e.g. decaying inflaton [ref] .

Considering the case of decays first, it has been shown in [ref] that the maximal lepton asymmetry $Δ$ which can be generated in decays of $N_2,3$ is of the order [equation] where $Δ_max=2/11$.

The spectrum and the number density of produced particles depends essentially on three parameters: the mixing angle with ordinary neutrino, the sterile neutrino mass and the lepton asymmetry of the Universe ($ΔL$) at the production time (for a recent analysis, see [ref] ; earlier considerations can be found in [ref] ).
